This is a mosque was designed by Emre Arolat Architecture by request of the Sancaklar Family who wanted a mosque overlooking the Buyukcekmece Lake just west of Istanbul Turkey. The mosque is embedded into the side of the hill so as to preserve the sense of belonging that this structure is part of the hill itself. The outside of the mosque is also built with light grey stone to further preserve the sense of nature and simplicity. The interior of the mosque is built in such a way that it seems to resemble a cave with its cascading stone ceilings and solid rock walls with soft lighting so as to create a feeling of peaceful worship. Due to the structure being made of natural materials and built partially within a hill is has natural insulation against heat transfer so as to lower energy costs.
